Introduction Nineteen consecutive patients underwent flexor hallucis longus (FHL) tendon transfer and medial displacement calcaneal osteotomy for the treatment of Stage 2 posterior tibial tendon dysfunction.

Methods The FHL tendon was utilized for transfer because it approximates the strength of the posterior tibiais muscle and is stronger than the peroneus brevis muscle. Seventeen patients returned for follow-up examination (average 18 months).

Results The AOFAS hindfoot score improved from 62/100 to 84/100. The subjective portion of the AOFAS hindfoot score improved from 31/60 to 49/60. Weight bearing pre-operative and post-operative radiographs revealed no statistically significant improvement for the medial longitudinal arch in measurements of lateral talo-first metatarsal angle, calcaneal pitch, vertical distance from the floor to the medial cuneiform or talo-navicular coverage angle. Three feet had a normal medial longitudinal arch and six feet had a longitudinal arch similar to the opposite side following the procedure. Patient satisfaction was high: 10 patients satisfied without reservations, six patients satisfied with minor reservations and one dissatisfied. No patient complained of donor defecit from the harvested FHL tendon.

Conculsions Despite the inability of the procedure to improve the height of the medial longitudinal arch, FHL transfer combined with medial diplacement calcaneal osteotomy yielded good to excellent clinical results and a high patient satisfaction rate.

In relation to the conduct of this study, one or more of the authors has received, or is likely to receive direct material benefits.
